Advice
- Check the lighting. Place a lamp on top of the desk and cover it with a sheet of paper. You can also light the room indirectly, by orienting the lamp against a wall in order to have a more subdued light and get good quality for your videos.
- Eliminate all background noise, such as radio and television, because the webcam microphone would capture and amplify them.
- Clothes with colorful patterns or stripes can distract attention from your face when recording. Red is the hardest color for video cameras to reproduce, while blue is the simplest. If you are dressed in white, your skin will look darker and the opposite will happen if you dress in black.
- If you don't think about your safety, people can use your webcam without your knowledge. When you're done recording, turn off the webcam and, if you don't want to take any chances, cover the lens with tape. Make sure the tape doesn't leave any residue on your computer.
